[QUOTE="biednick, post: 2828530, member: 123604"] 5 shots isn't enough to guarantee you have a representative sample. That 5 shot Berger group could double in size once you have enough rounds on target to give an complete picture of how that load will shoot. 10 shots gets you close, 30 shots more or less guarantees you have a representative sample. The Hornady group could also get bigger, but it will never get smaller. That's why low round count groups are useful for rejecting bad loads. There's no reason to shoot 30 rounds if 5 tells you it's not going to meet your expectations. I don't think anyone is saying your groups will all end up the same size if you shoot a statistically significant sample, but you need more than 5 shots to get a sample that shows the actual precision of your load.
